Rooted an AT&T phone. It was unlocked previously and had a T-Mobile SIM and was working great. Rooted to get hotspot. After rooting T-Mobile SIM working as well as hotspot, however, when I put in AT&T SIM phone says "No SIM card"!
AT&T Card will work ok in my iPhone.
Any ideas would be appreciated.

i have a question about galaxy nexus . after i rooted my GN , it does not read my sim card. (the phone is verizon lte and i have a t-mobile microsim) i checked the bootloader and the lock state is unlocked.
any ideas of what i should do now>
did you ever find out your answer? i unrooted my vzw galaxy and now it won't read a sim card.
try a normal simcard... not a microsim with an adapter
You have a Verizon Galaxy Nexus, which is carrier locked to Verizon, so your T-Mobile SIM won't work on it. The Verizon Galaxy Nexus is a CDMA phone, T-Mobile is a GSM carrier, so even if you carrier unlocked the phone, it still wouldn't work. And last but certainly not least, Your bootloader may be unlocked, but that doesn't mean that the SIM is unlocked; like I said earlier, that Verizon Galaxy Nexus is carrier locked.

How were you planning on using a CDMA/LTE phone on a network that only does GSM/HSPA? Not quite compatible. Different radios.

If you open up another thread with your specific issue we might be able to help you out but I don't want to derail this thread going into details about a completely different problem.
As for OP, that SIM will not work in any CDMA Galaxy Nexus because it is not a "global" phone. It only supports Verizon Wireless SIM cards.
Hey guys, i just received my Sony Ericson Xperia Arc S from japan (docomo). I just boot it, everything is fine until I insert the sim card, Im from Philippines and I'm new to android phones so i can't tell if this phone is unlock to all sim. I tried to scan the network and it detects all of the carrier in my country but i always prompted to this after i choose my carrier "your sim card does not allow connection to this network".
Your response will be much appreciated.
try with some other carrier sim cards on your phone...

Your phone does not have to be rooted to be unlocked. A carrier unlock is totally different. it allows you to use any sim card in your device. Rooting gives you access to the hidden file system that actually runs the phone.
I think you should contact your cell provider to replace the sim.
first try it with a different carrier's sim. if its working then ask your provider for a sim replacement. if its not working then your phone is probably carrier locked. (of course if reception is fine at your location)
I just purchased an S3 (AT&T version) and want to use it on StraightTalk but it needs to be unlocked inorder to use the StraightTalk SIM, I have seen the websites where I have to pay $XX.XX and they will unlock it with the IMEI #, but there MUST be a way to do this on my own, right??
If I root the phone, and install a custom ROM will that have any effect on the ability to unlock the SIM? or whats the process to do this on my own?? (Is it possible?)
thanks in advance
Search. There is a free method to unlock. Also, if you have an at&t straight talk sim, you don't need to unlock it.

Use your own compatible or unlocked GSM phone on America's best nationwide networks. Select a SIM or SIM bundle to get Unlimited* Data, Talk & Text. It's that easy.

He is right... Should work right out of the box. Just need to set your APN.
I'm trying to unlock my phone, I bought used on ebay, I found found a thread here that shows you how to unlock, but can't even do the first step. when I install a different sim card, I don't get the message Unlock, the phone reads the sim as a non support sim.
the sim I'm putting in the phone doesnt have service on it, Is this the reason the unlock message doesn't come up?
Please Help
Maybe your phone is already unlocked

I put a metro pcs sim that has service on it, but when I try to make a call, it say, not register to network, and or mobile network disconnected? Aso also tried to put the apn setting, but when I try to save the apn setting, they disappear??
Anyone have any idea?
Thanks for the reply
you can use free unlock from general http://forum.xda-developers.com/showthread.php?t=2024514
but of course you have to do it from uvkl1. but--you can do a nandroid, and after you unlock it, restore your backup! it will stay unlocked

Seems your phone's ROM/Radio mismatched or not for MetroPCS. This exactly happened to my phone also, until I flashed a new radio for my rom(I am using TMobile, flashed new TMobile ROM but not new Radio. Then it had the problems as you have now).
New sim fixed

Hey, I just need someone to point me to the right direction.
I bought my LG G2 off ebay last year, it came flashed to boost mobile. All I need to do is flash it back to sprint and unlock the GSM on the phone.
I just found this forum and don't know where to start in this process..
Im on 5.0.2
Software version LS980ZVI
Model # LS980
Thank you if you can help
this thread has everything you need
http://forum.xda-developers.com/sprint-g2/general/ls980-lollipop-update-root-sim-unlock-t3357837
After you install TWRP successfully but before you unlock the sim card, You can install the latest version ZVI that is already rooted
http://forum.xda-developers.com/sprint-g2/development/rom-ls980-stock-5-0-2-zvi-flashable-t3303163
for unlocking the SIM card I would use this procedure instead

Thank you !!
Since you are on ZVI already, you could try the steps in this thread

Hey I did all the steps and got it unlocked but I cant to get my simple mobile sim card to work.
When I select the network mode global I have full bars, but when I try gsm/umts all my bars go away.
The phone is reading the sim card, but im not able to make calls/text. I Also get a authentication error when I try to update the prl/profile settings
did you do the twoclick procedure to unlock the sim card?
did you edit your apn? from the dialer, dial ##3282#
i am on freedompop so i changed my apn to freedompop.foggmobile.com. Simple mobile might require it to be mvno.att.net or something like that( i used that for airvoice).

Yep I did the two click method but on both of my sims my phone refuses to connect/ find networks. I get emergency calls only.
I used a freedompop sim too and changed my apn to freedompop.foggmobile.com. but it still wont connect to the network. When I go into the freedompop messenger app it says. I dont have any data.

that;s strange. It worked for me as soon as I added my APN. Does your phone see the APN for three.co.uk and 3hotspot when you have the freedompop SIM in there?
I don;t even use the Freedompop Messenger app. i just use the sim for data. i can test the functionality of the sim slot because I have a freedompop CDMA/Sprint sim card along with a GSM one.
there are a couple of other ways to unlock the sim slot-they're all based on the same way so don;t know if anything will be different. there is a simfree.exe and there is a thread by someone named summercat for a 1 click procedure. try one of those

yep thats the first apn I see "three.co.uk"
im gonna tot back to zv8 and try this one more time or im just gonna go with ring plus or ting.
But thanks for all the help.
And you used ##3282# to add the new apn, correct?
I would go down to zve, then do the Ota update from sprint to zvg or zvh, then do the unlock and root and sim unlock. It's worked fine for me on zvh and zvi.

Yep, I enabled the lte/cdma, rebooted, then enabled gsm, rebooted and I got it to say freedompop on the lockscreen but after a couple of min. It went back to searching for networks.
im gonna try zve to zvg with the two click method
Good luck. The way you know it is supposed to be correctly installed is that your boot animation changes for the yellow sprint spark animation to some swirly wavy rainbow. The carrier image gets swapped to a gsm version.
